Disconnect the coaxial cable from J6010 on the
TUNER-MAIN Unit, then connect the 50-Ohm
Dummy Load to J6010.
Connect the Digital DC voltmeter (high-Z) to pin
3 of J6009 on the TUNER-MAIN Unit.
Turn off the [TUNE] switch, then set the Main
band (VFO-A) frequency to 24.900 MHz in the
FM mode.
Press the PTT switch, then rotate the [RF PWR]
knob for 50 Watts on the Wattmeter.
Adjust TC6002 on the TUNER-MAIN Unit for
minimum deflection on the DC voltmeter (less
than 0.1 V).
Release the PTT switch, then disconnect the 50-
Ohm Dummy Load from J6010 and re-connect
the coaxial cable to J6010.

Connect the 50-Ohm Dummy Load and Wattme-
ter to the "ANT 1" jack.
Turn off the [TUNE] switch, then set the Main
Band (VFO-A) frequency to 24.900 MHz in the
FM mode.
Press the PTT switch, then rotate the [RF PWR]
knob for 50 Watts on the Wattmeter.
Release the PTT switch, then disconnect the co-
axial cable from J6001 on the TUNER-MAIN Unit,
and re-connect the 50-Ohm Dummy Load to
J6001.
Connect the Digital DC voltmeter (high-Z) be-
tween TP6001 and TP6002 on the TUNER-MAIN
Unit, then turn on the [TUNE] switch.
Press the PTT switch, then adjust TC6001 on the
TUNER-MAIN Unit for 0 V (±0.08 V) on the DC
voltmeter.
Release the PTT switch, then disconnect the 50-
Ohm Dummy Load from J6001 and re-connect
the coaxial cable to J6001.
